About this map

The waters of San Pablo Strait and San Francisco Bay define this 1948 survey, showcasing a landscape of naval installations and vital ferry crossings. On the western shore, the State Penitentiary sits at Pt San Quentin, while the southern tip of the Tiburon Peninsula is anchored by the Tiburon Naval Net Depot and the neighboring settlements of Belvedere and Tiburon. This era precedes the modern bridge, relying instead on the Richmond-San Rafael Ferry to connect the Marin and Contra Costa coastlines.

Industrial activity is prominent around Richmond, where extensive Oil Tanks and the Richmond Pier reflect the city's role as a major maritime hub. Railroad lines, including the Northwestern Pacific and Atchison Topeka and Santa Fe, terminate at the water's edge, facilitating a complex network of freight and passenger transit. Educational landmarks like San Pedro Sch and Washington Sch serve the growing residential clusters appearing near the hills of San Pedro Santa Margarita Las Gallinas.
